DRAINAGE-TRAP.

Specification of Letters Patent.

Patented Feb. 16, 1915'.-

Application filed May 17, 1913. Serial No. 768,314.

Traps, of which the following is a specifica tion.

. This invention relates to drainage systems for bath-tubs, wash-basins, or the like, and more particularly to a new and useful trap employed in such systems, which has for its primary object the provision of a device of this nature which will drain the plumbing fixtures, such as bath-tubs, wash-basins, or the like, without the handicap of arrested air.

It is well known that traps of this nature are provided for the purpose of preventing foul or obnoxious sewer gases from passing upwardly through the drainage system and into the rooms wherein the plumbing fixtures are located, and that they are constructed in such a manner that a small quantity of water is retained in the pipe forming an airtight closure for the same. In the system of traps and drainage now employed, there is a certain amount of arrested air retained in the outlet pipe between the water in the trap and the basin, bath-tub, or the like. This arrested air prevents the water from flowing freely through the outlet, and also prevents the drain-pipe from carrying away its full capacity of waste-water.

The object of this invention is to provide a trap which will effectively prevent the entering of obnoxious or-foul sewer gases into the room, in which the plumbing fixtures are located, through the drain-pipes, and one which will eliminate the arrested air between the trap and the basin ortub and allows the drain-pipe to carry away its full capacity of waste-water, thus emptying the basin or tub in much less time and materially decreasing the amount of settlement left by thewater on the bottom of the tub or basin.

Another object of this invention is the provision of a trap which may be placed in any position between" the ceiling and the loor of a building and properly adjusted in I relation to the basin or tub; one which may be applied to any typeof plumbing fixtures, and which has a clean-,out plug located within in such a manner that the trap may be easily and effectively cleaned should-it become clogged and which clean-out plug will also serve a purposefor draining the pipes to prevent the water from freezing during cold weather.

A still further object of this. invention is the provision of a trap which by its particular form eliminates .the noise which is generally occasioned by the running of the water through the drain pipes leading from the bath-tub or other basin, in that, by' the elimination of the arrested air the gurgling and hissing noise occasioned by the water forcing its way through the space, wherein the arrested air is contained, is eliminated.

With the foregoing and other objects in View, this invention consists in such ndvel features of construction, combination. and arrangement of parts as will be hereinafter more fullydescribed, .illustrated in the accompanying drawings and claimed.

In describing the invention in detail, re-f- -erence will be had to the accompanying drawings wherein like characters of reference designate like or corresponding parts throughout the several views, and in which, Figure l is a view showing an improved trap in elevation and applied to a bath-tub; and Fig. 2 is "a central sectional view through the improvedtrap.

Referring to the drawings by numeral, '1 designates a bath-tub of any type now in use which has an outlet 2 formedin the bottom and near one end of the same, and an overflow -outlet 3 formed in one end of the sameand near the upper edge thereof. The outlet2 has a coupling or short piece of pipe 4 secured thereto in the ordinary manner, which pipe 4 is connected by means of a nut 5 to the upper end of the arm 6 of a Y- shaped member or pipe 7. The Y-shaped "member 7 has its arm 8 connected to a piece The lower end 12 of the Y-shaped memher 7 has internal screw-threads'13 formed thereupon which terminate at 14 ina smooth bore which extends outwardly through the arms 6 and 8, as is clearly shown in Fig. 2

the pipe 16, The collar 15 provides means whereby the distance between the adjacent ends of the Y-shaped member and the pipe 16 may be adjusted to suit conditions contingent with the house construction. The

pipe 16 is curved outwardly from the lower edge of the flange 17 and extends upwardly substantially at an acute angle to the vertical line of the collar 15, terminating in a flange 18 which has internal screw-threads 19 formed upon its inner surface. The screw-threads 19 form a means for connecting the pipe 16 to a short pipe 20, which pipe is inv turn connected to the vertical drain-pipe 21 which carries the waste-water down through the building directly to the drainage line or the sewer. v

A plug 22 is. inserted in an opening 23 which is formed in the lowermost portion of the pipe 16 and a short distance below the flange 17. The opening 23 forms a means for clearing out the various portions of the trap which is composed of the pipe 16, the collar 15, and the Y-shaped member 7 when the same becomes clogged and also for draining the pipes when desired, for instance in cold weather to prevent the water 1 from freezing therein, and it will be readily seen by referring to Fig. 2 of the drawings that a wire or other object may be inserted through the opening 23 and into any portion of the trap,.for instance, forced upwardly through the pipe 16 and through the pipe 20, thus completely opening the connection of the pipe 16 and the vertical drain-pipe 21, or it may be forced upwardly through either of the arms 6 or 8.

The water, which will be retained in the curved portion of the pipe 16 and interior of the collar 15, will form an airtight closure for the opening of the pipes and prevent any foul or obnoxious sewer gases from passing upwardly through the Y-shaped The collar 15 has a member 7 and into the room in which the bath-tub is mounted. A. certain amount of air will be retained in the pipes above the water (not shown) instead of in the curved portion of the pipe 16, but when the outlet 2 of the bath-tub 1 is opened and the water rushes downwardly through the pipe 4: and into the arm 6 of the Y-shaped member 7, it will force the air which is contained in the pipe upwardly through the arm 8, the pipe 9, and out through the overflow outlet 3, thus allowing the arm 6, the collar 15 and the pipe 16 to carry away its full capacity of waste-water and emptying the bathtub in much less time than would be possible if the water had to gradually force its way through an arrested amount of air within 7 the pipes and without the usual noises occzv sioned by the draining of the basin.

By the provision of the Y-shaped member 7 and connecting the same to the various drain-pipes, as has been hertofore described, all the T connections which are employed above the trap in drainage systems will be entirely eliminated; and as these T joints form the majority of sources of leakage in drainage systems, this feature will be to a great extent overcome.

In practicable fields, certain minor features of construction, combination, and arrangement of parts may necessitate alterations to which the patentee is entitled, provided such alterations are comprehended within the scope of what is claimed.

What is claimed is:

In a structure of the class described, a Y waste-head, a pipe extending upwardly and substantially at an acute angle to the vertlcal portion of said Y waste-head and a nipplethreaded in the lower end of sald upwardly extending pipe and 'into the lower portion of said Y waste-head for connectlng said, Y Waste-head to said upwardly extending'pipe.

In testimony whereof I aflixmy signature inpresence of two witnesses.
